Recommendations for my whisky tasting

I want to have a whisky tasting with say six whiskies.
I want to do it cheap but try and use some bottlings/finishes that regular drinkers may not have tried.
i.e. I thought I could use a Campbletown Loch 25. I definately dont want to use for example a Laphroig 10 because everyone will have tried it before,
Any ideas?

In fact, half the appeal of this malt is the fact it is so under-rated.

We have an expression here in Australia for people or things who go about their work brilliantly without making a fuss or song & dance about it. It's "Quiet Achiever". I think Cragganmore is a great example.
